Advent of Code Solutions in Rust

Run all tests:

$ cargo test

To run a particular binary crate:

$ cargo run -p <crate>

or cd into that crate and cargo run there.

This repo contains a crate called aoc_utils. Documentation is available here.

You can use it within your own Rust project by adding this to your Cargo.toml:

aoc_utils = { git = "https://github.com/bpshaver/advent-of-code-rust", branch = "main" }

PRs are welcome.

This repo includes a template for new Rust crates using the Python project template library cookiecutter. To use it:

$ pip install -r requirements.txt
$ python -m cookiecutter template

And give the new project a name like aoc23_02 for e.g. Advent of Code 2023 day 2.

The newly generated crate will not be part of the workspace defined in the Cargo.toml at the root of this repo. To do so, add the crate under the [packages] section in that file and remove the empty [workspace] section from the new project's Cargo.toml file.

So that the newly generated crate can compile, there is a placeholder input.txt in a newly generated crate. You should replace this with an input.txt file from the Advent of Code website.

I wanted to solve Part Two by making the "card" and "hand" structs generic with respect to whether jokers are allowed, then have scoring and ordering methods dispatch based on the value of the const generic const JOKERS: bool:

part_one = generic_solution<false>(...)
part_two = generic_solution<true>(...)

Unfortunately, rustc (1.72.0) doesn't yet consider the true and false implementations of a trait with const generic booleans to be exhaustive: issue.

the trait bound `HAND<JOKERS_ALLOWED>: FromStr` is not satisfied
            the following other typer implement trait `FromStr`:
                                                     Hand<false>
                                                      Hand<true>
                                                         (E0277)
